What I like to do

My main interest is traveling. I first started out in Paris. I stayed there for a good while. Then in the year 1620 to 1628 I was in different parts of Europe. I was in  Bohemia in 1620, Hungry in 1621, Germany, Holand, and France in the years 1622-1623. The year 1623 I spent in Paris, France.Then I was in Italy, mostly Venice, for 2 years. Then i returned to France in the year 1625.

Another hobby I like is writing. I like to write  about math, science, and philosophy. That is what most of my books or treatise are about. I spent a lot of time writing and even editing my own work. I had some other scientist and philosophers help me check my work. You can never be to carful.
